Due to the outstanding physicochemical properties arising from its truly two-dimensional (2D) planar
structure with a single-atom thickness, graphene exhibits great potential for use in sensors, catalysts,
electrodes, and in biological applications, etc. With further developments in the theoretical understanding
and assembly techniques, graphene should enable great changes both in scientific research and practical
industrial applications. By the look of development, it is of fundamental and practical significance to
translate the novel physical and chemical properties of individual graphene nanosheets into the
macroscale by the assembly of graphene building blocks into macroscopic architectures with structural
specialities and functional novelties. The combined features of a 2D planar structure and abundant
functional groups of graphene oxide (GO) should provide great possibilities for the assembly of GO
nanosheets into macroscopic architectures with different macroscaled shapes through various assembly
techniques under different bonding interactions. Moreover, macroscopic graphene frameworks can be
used as ideal scaffolds for the incorporation of functional materials to offset the shortage of pure
graphene in the specific desired functionality. The advantages of light weight, supra-flexibility, large
surface area, tough mechanical strength, and high electrical conductivity guarantee graphene-based
architectures wide application fields. This critical review mainly addresses recent advances in the design
and fabrication of graphene-based macroscopic assemblies and architectures and their potential
applications. Herein, we first provide overviews of the functional macroscopic graphene materials from
three aspects, i.e., 1D graphene fibers/ribbons, 2D graphene films/papers, 3D network-structured graphene
monoliths, and their composite counterparts with either polymers or nano-objects. Then, we present
the promising potential applications of graphene-based macroscopic assemblies in the fields of electronic
and optoelectronic devices, sensors, electrochemical energy devices, and in water treatment. Last, the
personal conclusions and perspectives for this intriguing field are given.请小伙伴们下载后给个好评!![Chem Soc Rev热点综述:石墨烯基宏观装配和结构]()
